State Park · Missouri
A geologic showpiece above the Lake of the Ozarks: the stone ruins of a turn-of-the-century castle, a 100-foot natural bridge, sinkholes, a huge spring, and more than 15 miles of bluff-top trail.
Field briefing
Ha Ha Tonka State Park changes fast with season and elevation.
Before you go
The park is day-use only, so book a campsite elsewhere on the lake if you want to stay over.
The landmarks worth the trip. Tap any photo to enlarge.
Weather, crowds, and what the season changes about the trip.
Mild and green, with wildflowers, full spring flow, and the most comfortable hiking temperatures.
Pack Layers, grippy footwear for boardwalk stairs, and a rain shell.
Hot and humid on the exposed bluffs, with busy weekends tied to the Lake of the Ozarks.
Pack Water, sun protection, and an early start before the midday heat.
Crisp and colorful, the standout window for the castle overlook and the trail system.
Pack Warm layer, headlamp for shorter days, and footwear for leaves on stone steps.
Cold and quiet, with bare-tree views into the sinkholes and the gorge.
Pack Insulation, traction for icy boardwalk steps, and a check on trail conditions.
Castle ruins and the Dell Rim overlook
The signature scene: the stabilized stone walls of a 1905 mansion that burned in 1942, perched on a bluff with a long view over the Lake of the Ozarks. The short Castle and Dell Rim trails reach it.
Natural Bridge and Colosseum
A 100-foot stone arch and a deep collapsed-cave sinkhole on the Colosseum Trail, a short figure-eight loop through the park's karst geology.
Spring Trail and the grist mill
A longer walk down to Ha Ha Tonka Spring, one of Missouri's largest, past the remnants of an old grist mill and along the cool water at the head of the lake.
Keep one flexible slot in the day, because weather, parking, and energy usually decide more than the map does. For one day in Ha Ha Tonka State Park, make Castle ruins and the Dell Rim overlook the non-negotiable, add Natural Bridge and Colosseum only if the first stop runs clean, and keep Spring Trail and the grist mill as the flexible finish.

Ha Ha Tonka has no campground, so base in nearby Camdenton or at Lake of the Ozarks State Park across the water, which has reservable Missouri State Parks campsites. Camdenton and the wider Lake of the Ozarks area carry the bulk of the hotels, rentals, and restaurants.
Camping reservations
The park is built for day visits to the ruins, sinkholes, and spring, with no campground of its own. For an overnight, reserve a site at Lake of the Ozarks State Park or stay in Camdenton.

Getting there
Arrival note
Ha Ha Tonka is just southwest of Camdenton in central Missouri, near the Lake of the Ozarks and about three hours from both St. Louis and Kansas City.
Car strategy
A car is required, and the trailheads for the castle, sinkholes, and spring sit a short drive apart inside the park.
Pair this with lodging: the simplest base is the one that removes a real morning problem, not just the one nearest the map pin.
No. Ha Ha Tonka is a day-use park with no campground. For an overnight, reserve a site at nearby Lake of the Ozarks State Park or stay in Camdenton, then visit Ha Ha Tonka as a day trip.
No. Like all Missouri state parks, day-use entry is free. Missouri charges only for camping and certain facilities, and Ha Ha Tonka has no campground.
Short. The Castle and Dell Rim trails reach the ruins and the bluff overlook in well under a mile, with stairs and boardwalk sections along the way. Linking in the Colosseum and Spring trails makes a fuller half-day loop.
